TECHNICAL FIELD

The present invention relates to wireless communication devices that include image capture devices.

BACKGROUND OF THE INVENTION

Two commonly-used techniques for navigating to destinations of a computer network, such as the Internet, include: (a) manually entering a Uniform Resource Locator (URL) into a command line of a Web browser, and (b) clicking on a hyperlink displayed by a Web browser. Manually entering URLs having a long sequence of characters may be undesirable for some end users.

Various recently-proposed techniques for navigating to destinations of the Internet use bar codes to obviate manual entering of URLs. U.S. Pat. Nos. 5,930,767, 5,938,726, 5,940,595, 5,969,324, 5,986,651, 5,995,105, 6,032,195 and 6,081,827, which are assigned to Motorola, Inc. and are hereby incorporated by reference into the present disclosure, disclose various approaches to computer network navigation using bar codes.

U.S. Pat. No. 5,978,773 to Hudetz et al. discloses that a bar code used to identify a product (e.g. a Universal Product Code) also may be used to access remote computers on a network. To access an Internet resource relating to a particular product, a user enters the product's UPC. A database retrieves the URL (Uniform Resource Locator) corresponding to the UPC. The URL is used to access the Internet resource.

U.S. Pat. No. 5,804,803 to Cragun et al. discloses a method which includes determining whether or not a code is a UPC. If the code is a UPC, URL information stored in a product database is requested using the UPC as an index. If the code is not a UPC, the code is considered as a URL string which may or may not be in an abbreviated form.

International Publication No. WO 00/16211 to Digitalconvergence.com, Inc. discloses a method for interfacing scanned product information with the manufacturer of the product over a global communication network. A product identifier is accessed at a source location on the network. Routing information is appended to the accessed product identifier. The routing information defines a remote location on the network. The product information is transmitted from the source location to the remote location in accordance with the appended routing information.

Examples of computer-readable communication media include, but are not limited to, an electronic medium, an optical medium and an electromagnetic medium.

As indicated by block 30, the method optionally comprises receiving one or more signals indicating one or more user-selected portions of the image. The end user selects the portion(s) of the image to contain one or more of the at least one object 14, and to exclude at least another one of the at least one object 14. The one or more of the at least one object 14 in the user-selected portion(s) include those for which the user desires to perform an associated task.

To provide the aforementioned signal(s), the network access apparatus 20 comprises a user input interface 32. The user input interface 32 senses one or more user-initiated actions which indicate the user-selected portion(s) of the image, and generates the signal(s) based thereon. Preferably, the user input interface 32 comprises a touch-sensitive screen of the display device 24. In this case, the end user may use a stylus or a finger to draw one or more closed loops around one or more of the at least one object 14 to make a selection thereof. Either in addition to or as an alternative to the touch-sensitive screen, the user input interface 32 may comprise any combination of a telephone keypad, one or more buttons, a mouse, a trackball, a pointing stick, a touch pad, a joystick, a keyboard, and a voice input device. The end user may select the portion(s) of the image using any of the aforementioned input devices. Using a voice input device, for example, a user may speak a name and/or a description of the at least one object 14 to make a selection thereof.

As indicated by block 34, the method comprises providing a menu of a plurality of object classes. The plurality of object classes in the menu may comprise a person class, a product class, a company class, a location class, an event class, or any combination thereof. The menu may be provided locally by a memory 36 and/or remotely by a server system 40 via a computer network 42. The menu is displayed by the display device 24.

If the menu is provided remotely, a transceiver 44 may be directed by the processor 26 to facilitate navigation to the server system 40 via the computer network 42. Thereafter, the transceiver 44 may be directed by the processor 26 to receive the menu from the server system 40 via the computer network 42. Examples of the transceiver 44 include, but are not limited to, a wireless radio frequency transceiver, a wireless modem, a dial-up modem, a cable modem and a network interface card. Examples of the computer network 42 include, but are not limited to, an internet, an intranet and an extranet.

As indicated by block 46, the method comprises receiving an object class selection from the menu. The object class selection is made by the end user using the user input interface 32.

As indicated by block 50, the method comprises providing at least one task menu specific to the object class selection. Each task menu provides a plurality of tasks specific to a class of objects. Specific examples of task menus are subsequently described with reference to FIG. 3. The at least one task menu may be provided locally by the memory 36 and/or remotely by the server system 40 via the computer network 42. The at least one task menu is displayed by the display device 24.

As indicated by block 52, the method comprises receiving a task selection from the at least one task menu. The task selection is made by the end user using the user input interface 32.

As indicated by block 54, the method comprises facilitating a task associated with the at least one object 14 based on the image and the task selection. The image and the task selection may be processed remotely by the server system 40 to facilitate the task. In this case, the transceiver 44 is used to communicate the task selection and at least part of the image to the server system 40 via the computer network 42. The at least part of the image may consist of either the entire image or the user-selected portion(s) of the image. Optionally, the entire image is provided to the server system 40 along with data indicating the user-selected portion(s).

The server system 40 provides an object recognizer 56 capable of recognizing objects absent of an optical code in a received image. Preferably, the object recognizer 56 is capable of recognizing objects absent of an optical code and objects having an optical code which is not present in the received image. For example, the object recognizer 56 may be capable of recognizing objects absent of either a one-dimensional or a two-dimensional bar code, and objects having either a one-dimensional or a two-dimensional bar code which is not present in the received image. Various known object recognition methodologies may be employed by the object recognizer 56, as those having ordinary skill in the art of image processing will recognize.

Preferably, the object recognizer 56 is capable of recognizing both substantially planar objects and substantially non-planar objects. Examples of substantially planar objects include, but are not limited to, fingerprints, a printed page in a publication, a printed poster, and a printed sign. Examples of substantially non-planar objects include, but are not limited to, human faces, products in visually recognizable packages and/or containers (e.g. cans, bottles, boxes and bags), visually-recognizable products themselves, landmarks and buildings.

It is further preferred that the object recognizer 56 be capable of recognizing objects independent of their absolute and relative locations in the received image. Further, the object recognizer 56 preferably is capable of recognizing objects independent of their orientation and/or size in the received image.

The object recognizer 56 may use a user-spoken or otherwise user-entered name and/or description of the an object to assist in its recognition and/or selection. For example, the end user may say “battery” to select a battery within an image of a plurality of objects. The object recognizer 56, in turn, would attempt to recognize a battery within the image.

The server system 40 further provides a task facilitator 60 responsive to the object recognizer 56. The task facilitator 60 facilitates performing a task associated with the task selection and at least one recognized object in the image. The task facilitator 60 either may facilitate a task for a single recognized object, or may facilitate a respective task for each of a plurality of recognized objects.

Each task may be at least partially facilitated using an associated resource of the computer network 42. For example, one of the tasks in the task menu may be facilitated for the at least one object 14 using a computer network resource 61.

The task facilitator 60 may translate a combination of a recognized object and a task selection to an associated computer address of the associated resource. The task facilitator 60 may comprise either a database or an associative memory which associates a respective computer address to each of a plurality of different object/task selection combinations. Examples of each computer address include, but are not limited to, a URL, a uniform resource name (URN), a uniform resource identifier (URI) and an Internet protocol (IP) address. Potential computer network addresses include all of those available via the World Wide Web.

Optionally, the server system 40 provides an optical code detector 62 capable of detecting and decoding an optical code in a received image. In this case, the task facilitator 60 is responsive to the optical code detector 62 to facilitate a task based on an optical code/task selection combination. Examples of the optical code include one-dimensional and two-dimensional bar codes. The optical code may comprise a product code such as either a UPC bar code, an EAN (European Article Numbering) bar code, a JAN (Japanese Article Numbering) bar code or ISBN (International Standard Book Number) bar code. The task facilitator 60 may comprise either a database or an associative memory which associates a respective computer address to each of a plurality of different optical code/task selection combinations. Potential computer addresses resources include all of those available via the World Wide Web.

Optionally, the task facilitator 60 also associates a respective software agent with each object/task selection combination and each optical code/task selection combination. Each software agent is usable to assist in performing an associated task. Alternatively, the computer network resource associated with a combination may provide a software agent.

Using the aforementioned components, the server system 40 may facilitate the task as follows. The server system 40 receives the task selection and the at least part of the image via the computer network 42. As used herein, the phrase “received image” is meant to indicate either an entire image or the user-selected portion(s) of the entire image received by the server system 40. In other words, if an image is received along with data indicating the user-selected portion(s) of the image, the “received image” indicates the user-selected portion(s) of the image.

The optional optical code detector 62 serves to determine if an optical code is present in the received image. If so, the task facilitator 60 determines one or more computer addresses associated with one or more combinations of the task selection with one or more optical codes detected in the received image.

The object recognizer 56 serves to attempt to recognize one or more objects absent an optical code in the received image. Preferably, the one or more objects absent an optical code are recognized without use of optical character recognition. The task facilitator 60 determines one or more computer addresses associated with one or more combinations of the task selection and one or more objects recognized in the received image.

The server system 40 may communicate each of the computer addresses determined by the task facilitator 60 to the network access apparatus 20. This act may comprise communicating a single computer address either if one optical code is detected in the received image and no objects are recognized in the received image, or if one object is recognized in the received image and no optical codes are detected in the received image. Alternatively, this act may comprise communicating a plurality of computer addresses either if a plurality of optical codes are detected in the received image, if a plurality of objects are recognized in the received image, or at least one optical code is detected in the received image and at least one object is recognized in the received image.

The processor 26 directs the transceiver 44 to receive one or more computer addresses communicated by the server system 40 via the computer network 42. To assist in facilitating a task, the processor 26 directs navigation to a computer network resource using a received computer address. This act may include automatically using a computer address to substantially immediately facilitate computer navigation to a computer network resource. Alternatively, this act may include storing one or more computer addresses to facilitate a subsequent, delayed computer navigation to one or more computer network resources.

The transceiver 44 may send one or more messages to attempt to link to a server which provides the computer network resource, and to request the computer network resource. Further, the transceiver 44 may receive the requested computer network resource in the form of one or more response messages from the server. Media content received from the computer network resource may be processed by the processor 26 based on markup data received from the computer network resource. The processor 26 provides a display signal to the display device 24 to display the marked-up content. The requested computer network resource may be a Web page, for example, having visible content and/or audible content.

Acts performed by the aforementioned components of the server system 40 may be directed by computer-readable content of a computer-readable medium. Examples of the computer-readable medium include a computer-readable storage medium and a computer-readable communication medium. Examples of computer-readable storage media include, but are not limited to, a computer memory, a magnetic floppy disk, a magnetic hard disk, and an optical disk. Examples of computer-readable communication media include, but are not limited to, an electronic medium, an optical medium and an electromagnetic medium. The server system 40 may comprise either a single server computer or a plurality of computers to provide the aforementioned components.

As an alternative to using the server system 40, the image and the task selection may be processed locally by the network access apparatus 20 to facilitate the task. In this case, the processor 26 is programmed to locally perform the herein-described acts of the object recognizer 56, the task facilitator 60, and the optical code detector 62. In this case, the software agents for the tasks may reside in the memory 36. Optionally, the memory 36 comprises a memory card or an alternative medium which is removable from the network access apparatus 20.

Regardless of whether the image and task selection are processed remotely or locally, the associated task associated with the object may be stored as either a custom or a personalized task for future re-use or repetition. Some customized or personalized task options may be shared to other users via the server system 40. An option may be provided to define and/or configure new task options by either the user or a service provider. New task options may be made available immediately or delayed for later use.

Flow of the method may be redirected back to block 10, wherein either an image of another scene is captured and processed based on a task selection, or the same image is processed based on a different task selection, to perform one or more other tasks (not specifically illustrated).
